GILPIN MOORE, OF ROCK ISLAND, ILLINOIS.

PLOW.

SPECIFICATION forming part of Letters Patent No. 418,468, dated.December 31, 1889.

Application filed April 5, 1888.

To all whom it may concern.-

Be it known that I, GILPIN MOORE, of the city of Rock Island, in thecounty of Rock Island and State of Illinois, have invented, a new anduseful Improvement in Plows, of which the following is a specification.

My invention relates to improvements in plows, whereby the two handlesare held rigidly in a fixed relationship to each other, both beinghinged and made to turn laterally upon a common pivot in order to passby trees, stumps, or other obstructions, and when so turned to right orleft or placed cen tral they may readily be secured in said position bymeans of an eyebolt and thumbscrew.

My invention also relates to an adjustable defiection-bar located at thefront end of the plow-beam for changing the effect of the draft, wherebythe plow is made to run more or less to or from land, or deeper orshallower, as may be desired.

I attain these objects by the mechanism illustrated in the accompanyingdrawings,in which- Figure 1 is a side view of the landside of a plowembodying my invention. Fig. 2 is a top view of the same parts. Figs. 3and 4 are plan views of different positions of the adjustabledeflection-bar; Fig. 5, an edge View of the adjustable disk forsupporting the deflection-bar; Fig. 6, a quartering view of same partsviewed in direction of the an row 0 in Fig. 5.

Similar letters refer to similar throughout the several views.

A is the beam of the plow; 1-3, the moldboard; O O, the handles 5 D, theground-bar; E, an adjustable deflection-bar; M, the handle-support; II,an eyebolt for holding the adjustment of the handles, and N the adjustable disk with which to effect a radial and longitudinal adjustmentof the deflectionbar E. This bar consists of a perforated bar partiallyembedded in a groove cut into the front face of the adjustable disk, andat its outer end carrying the draw-chain g, which passes through a largeopening in the bar, as seen at r in Fig. 3. This bar may be adjustedlongitudinally so as to bring either of the small perforations intoposition to take the center bolt f, and at the same time the bar,

the disk, and the chain may be turned to the position g, (shown indotted lines in Fig. 2,) as also to all points of the circumferencearound the clamping-bolt f, and be there rigidly held by the stud I,Fig. 2, entering one of the small holes in the rear face of the disk N,as seen in Fig. l. Figs. 3 and 4 show this bar at different positions ofthe circumference, and also different longitudinal adjustment relativelyto the disk N. The pur pose of this deflection-bar is to adjust thedraft of the plow by deflecting it from a right line, thereby causing itto run to or from land, and deeper or shallower, as may be desired. InFig. 3 this bar is represented in combination with the adjustable diskand center-bolt f, as viewed in the direction indicated by the arrow 0in Fig. 2. The two handles are held in a fixed relation to each other attheir upper ends by the tie-rod "L, and at their lower ends areformulated into a vertically-pivoted shank L, the lower end of which ispintled to a bracket is, secured to the ground-bar D, the upper portionof the shank passing through the handle-supporter M at the point a nearto the beam of the plow, thus affording the handles two positivepivot-bearings to support them. The supporting-arm M at its upper endcontains an eyebolt with thumb-screw H, and through the eye 6 of thisbolt a curved tierod m passes and is made fast to both handles. By thisform of construction it will be seen that the two handles may be turnedto either side at will, as represented by the dotted lines a c or c c",and that by means of the eyebolt and tie-rod they may be securely heldat any point of lateral adjustment by the hand of the plowman, thusenabling him to carry them past obstructions on either side. Thesupporting-arm M is bolted rigidly to the plowbeam, whence it extendsbackward and upward to the tie-rod m. By means of this rigid arm thehandles are supported at a sufficient distance from the pivotal pointsto give them sufficient stiffness and at the same time admit of thelateral adjustment inclicated by the dotted lines in Fig. 2.-

I do not claim, broadly, the laterally-adjustable handles 0 O, as I amaware that handles having such adjustment have been known prior to myinvention; nor do I claim,
